D-62
MOTOROLA
This read-only bit reflects the logic state of the clock input pin CTM2C. Writing to this
bit has no effect nor does reset.
This read-only bit reflects the logic state of the modulus load input pin CTD9. Writing
to this bit has no effect nor does reset.
These read/write control bits select which edge on CTD9 triggers the modulus load
input. Refer to Table D-42.
These read/write control bits select one of the six CPSM clock signals (PCLK[1:6]) or
one of two external conditions on CTM2C to clock the modulus counter. The maximum
frequency of an external clock signal is f
Two time base buses should not be driven at the same time.
